What is Selenium:
Selenium is a free automated testing framework used to validate web applications across different browsers and platforms. We can use multiple programming languages like java, C#, python... to create Selenium test scripts.
Selenium has 4 components:
Selenium IDE
Selenium RC
Selenium Webdriver
Selenium Grid
Why do we use selenium for automation?
The need for selenium arises from the limitation of manual testing. As applications grow in complexity and require frequent updates, manually testing every feature becomes time - consuming and prone to human error. Selenium addresses this issue by enabling automated test scripts that can be executed repeatedly with high accuracy. It supports multiple browsers like Chrome, Firefox, Safari...
Selenium closely mimics real user behavior on web applications. Unlike some testing tools that operate at the code level, Selenium interacts directly with the browser, ensuring realistic testing scenarios.
It also supports integration with testing framework such as pytest, unittest etc..
What is the relevance of Selenium in automation testing using python?
Selenium with python enables quick test development , faster execution, and easier maintenance of test scripts. It also supports data - driven testing , allowing testers to run the same test with multiple sets of input data.
